Ford is working to reduce greenhouse gas emissions from its supply chain. It plans to survey its top 35 suppliers on their energy use and emissions, representing $20 billion in procurement. This will help Ford understand its supply chain carbon footprint and create a carbon management approach. Ford aims to reduce its overall emissions by 30% by 2020 in response to pressure from investors. By collaborating with suppliers on efficiency, Ford hopes to put pressure on low performers and gain cost reductions as suppliers improve operations.
